Quality

  • Familiarity: I've put it through the wringer

I have had a few pairs of the phd socks over the years, but the current version has highest quality construction. Unlike previous versions this iteration has the seams in better locations for a more durable feel. I have had other phd socks rip but this one seems like it will last for years to come. Breathable and soft, smart wool really knows their socks!

Perfect

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: XL

First of all, you absolutely cannot go wrong with SmartWool socks of any style. These are exactly as described. They are on the thinner side of SmartWool's line of socks, but that is exactly what I wanted.

summer option

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Bought these for my summer days. I have thicker ones for winter. The material is excellent and feel great on your foot. They are lighter so I haven't worn them in the colder winter days yet.
